- Refactors `runjob` and `jobstatus` commands. Now, the main
`cloudos` tool have the `job` subtool which in turn has its
`run` and `status` commands performing the previous
functionality. This way, now the tool can be used with:
`cloudos job run [OPTIONS]` and `cloudos job status [OPTIONS]`.
- Adding `--wait-completion` option to `cloudos job run` command,
to be able to wait until job completion or failure.
